WEIGHING MECHANISM.

Application filed June 20,

I have exemplified my invention as applied to, bakers use in connectionwith mechanism for providing a charge of flour properly sifted andweighed and ready to be charged into the receptacle in which it is to beutilized, which may for instance be the container of a dough mixingmachine.

It is the object of my invention to provide new and improved meanswhereby to weigh the material, exemplified as flour, while beingreceived in a container, and ncw'and improved means whereby when thedesired weight of material has been received in the container, thefeeding of the material is antomatically stopped in novel manner;further, to provide novel means for advancing the material toward acontainer in which the same is wei 'hed, and to provide novel operatingmeans for said devices, and novel means whereby the operation of thesame is automatically interrupted; and, further, to provide novel meansfor controlling the operation of said devices.

It is the object of my invention. further, to provide an electricallyoperated control member arranged to be placed in inte .fering relationwith a movable member deriving its power from the power of the machine,whereby the. power of the machine is eiiective to perform the functionofintcrruption in the advancing or feeding movement of the material, andwhereby the control forsuch last--' named means is normally free ofconnection with said powerv means.

The flour to be used in the baking is contained in a suitable storagecompartment,

141- of Fig. 13, showing the finger ad- Y shaft has a conveyoi1-screw 74fixed thereto,

exemplified as a flour-bin 31, which is provided with suitable agitatorblades on a shaft 33 journaled in the bin, and provided with asprocket-wheel 3%,. A sprocket-chain 35 passes about said sprocket-wheeland a sprocket-wheel 36 on a sliaft 39, journaled in bearings in theframe of the bin. A conveyor screw -10 is fixed to the shaft 30 andoperates in a trough 41 in the'bottoiii of the bin for conveying theflour in the bin through an opening 42 in the end of the bin, and achute 43 communicatingtherewith, into the'bottom of an elevator A l.(See Figs. 2 and 9.) Y V The shaft 39 is exemplified as a driven shaft,so that when rotation of said shaft ceases, the feeding of flour fromthe bin to the elevator will also cease. 39 mayhave' an extension shaft15 in the bottom of the elevator. The shaft i5 is journaled-in bearings46 in the elevator casing. A coupling 47 connects the shafts '30 and45." g

.The elevator is exemplified as comprising a casing 51, in which asprocket-chain having. conveyor-buckets 53 thereon, is arranged tooperate. The sprocket-chain is received about a sprocket wheel 54: fixedto the shaft 45, and about a'sprocket-wheel fixed to a shaft 56,journaled in bearings 57 in end-plates 58 fixed to the casing, andreceiving rotation in manner to be presently described. The elevatorcasing is provided with'a door 59.. (See Figs. 2, 8 and 20.)

The conveyor-buckets are arranged to discharge into a trough 61 in thecasing. The trough is continued as a conveyor-pipe 62, whichextendslaterally from the casing so as to communicate with a flour sifter 63,the 'pipe being supported inffianges 64, 65. respectively, on one of theend-plates'and on the body'of the sifter." The sifter is rigidlysuspended by hangers 68 from a board 69. A shaft 71 is located in thetrough and conveyor-pipe, and isexeinplified as joui'naledin a bearing72 in the outer end plate58 and in a bearings73 on the outer wall of thebodyof' the floursifter. The

for conveying the flour discharged into said trough into the Sifter. V

The sifter comprises a Wall 77 in which there is a sieve 78. (See Figs.2 and 7.)

The shaft 71 has agitatorarms 79 and agitator blades 80 fixed thereto,for stirring the flour and moving the same across the inner faceofthe'sieve 78, 'so' as to sift the flour through said sieve as long assaid agitation continues, the sifting of the fiour' ceasing when saidagitator blades cease rotating. 7

A charging receptacle, exemplified as a hopper 81 is arranged to receivethe'flour from said sifter, through a flexible conduit 82, whichmay be afabric tube, preferably accordion-pleated, having its respective endsThe shaft fixed to the flange 83 of the sifter anda flange 84 ofa cover85 of the hopper, which cover may be removable. -This tube is of lightmaterial and readily adapts itself to the positions of the hopperwithout afi'ectingthe weightrcadings of the contents of the hopper.

The hopper is provided with slanting walls 86, for directing thecontents thereof to a'discharge opening 87 in the bottom of the hopper,which is normally closed by a gate 88, slidable in guideways 89 and onrollers 90 in the mouth of the hopper. Figs. 2, 3 and 7.) The opening ofthe gate will cau-se the charge of flour in the hopper to be'discharged'at the desirable point. The

hopperis exemplified as discharging into a dough-mixingmachine 91. Forconvenience of directing the charge into the dough-mixing machine, thebottom of the hopper has See a flexible conduit 92 fixed thereto, asabout the flange 93 of the mouth of the hopper, the bottom of theconduit being received in the mouth 9% of the cover 95 of thedoughmixing machine, 7

The dough-mixing machine may comprise a. shaft 101, journaled inbearings102, 103, of the frame 104, and having thereon mixer-- wings105. (See Figs. 2 and 7.) r A driveshaft 106 is journaled in bearings107 on said frame and a bearing 108 of a bracket 109, andhas a pinion110 fixed thereon,

which meshes with a gear 111 fixed to theshaft 106 with a pulley 116; abelt 117 being received abouti-said pulley and about a pulley 118'on ashaft119. The shaft 110 is journaled in'a bearing 120 on a bracket 121extending from the conveyor-pipe 62, and in bearings 122, 123, on theend-plates 58 of the elevator casing. (See Figs. 2 and 20.)

A clutch 131 is arranged to transmit'rotation or cause cessation of suchtransmission to the conveyor mechanisms, including the conveyors in thebin, in the elevator. and

in the troughand pipe, as well'as the agi-' tatingineans in the sift-er.I (See Figs. 1 and 20.) This clutch is shown as a cup friction clutch,comprising a cupanember 132, in

which the shaft rotates loosely, the same being held in endwise relationon said shaft between the bearing 123 and a collar 133 secured to saidshaft. A cone-member 136 of'said clutch, shown as the movable member ofthe clutch, is arranged to rotate wit-h said ha t a d to ha ax almovement th reon,

lVhen the clutch 131 is in engagement,

power is transmitted from the shaft 119 to r the sprocket-wheels 1445, 115, for operating said conveyor mechanisms and agitators. and when saidclutch is released, theoperations of said conveyor mechanisms, whichinclude the agitators, cease,'tor causing cessation of feed of flourinto the hopper, such clutch release being effected when the desiredweight of flour has been fed into the hopper.

The weight of the n'iaterial, exemplified as flour, in the receptacle,instanced as the hoppen is indicated on scales 151, the hopperbeingyieldingly mounted with relation to said scales so as to indicatethe-movements of the hopper induced by weight therein upon the scales.Thus hanger rods 152, 1-53, are fixed to a suitable support, as to theboard 60, fixedto the ceilingof the room. A tube is fixed to the rod152, as by means 01 set-bolts 155, and a tube 156 is fixed to thehanger-rod 153, as by means of set-bolts 157. The respective tubes havelugs 158, 159, extending therefrom, provided with sockets 160, 161.

Scale levers 162, 163, have knife-edge lugs 161-, 165, fixed thereto,which rest on the.

(See Figs.

bottoms of the sockets 160, 161. 18 and 10.)

The hopper is provided with a steadying: means to prevent unduevibration thereoi, shown as a link 167 at each side ot'the hopper.articulated with a bracket 168 at 169 and with the hanger tube at 170,the brackets being secured to the hopper. and a.)

The hopper is-provided with a tube 171. which extends therethroue h atits middle. A rod 172 extends through said tube and is (See F1 gs. 2

spaced therefrom throughout its length. ex- 7 cent that at itsrespective endsit is provided with knife-edge blocks 173, 11 1, on whichthe tube rests.

(See Figs. 1, 2, 3, 1

The rod isconnected at its respective ends with the levers162,l63. the

extending therefrom, on which counter-bad ance weights 177, 178, areadjustal'ilv threaded, nuts 1T9, 180, clamping the counterbalanceweights in adjusted positions.

The scale ciinnprises membe s T81. 18:2. which have relative movementbetween them. The member 182 is exemplified as secured to thehanger-tube 156, as hy having an extension 183 provided with an eve 181through which a bolt 185 is received and threaded into a bracket 186 ofthe hanger tube. (See Figs. 3 and The men'iher 181 is provided with anextension 184 in which there is an eye 188. it link 101 con- .nects saidmember 181 with the scale-lever 163, this link having a fork 192 at itslower end connected with the eve 188 by means ot a pin 193 receivedthrough holes in said tori; and said eye. The upper end of the linkprovided with an eve 105 in which a knifeedge lug 196 on s scale-leveris received.

Springs 201, 22. c nect with the respective members of the scales, the uof thesprings be' 1' shop ed in eyes 203 on the meu'iber 181 and thelower end of the sprii being formed as ho 204, received thioug'h")ertures 205 in member 182. (See 1 i; 12 and Movements between themembers is guided by providing a guideway 206 on the memher 182 in whicha lit on the member 181 is received. The ex ension 208 in whichtheguideway is located, has a bar 209 tending therefrom, received in aguidewrrv 210 in the, member 181.

The scales comprises a dial-plate which is fixed to the member 181, anda dialplate 216 which adjustable with relalhm to the dial-plate 215 torthe desired weight of contents oi the hopper, and is also movable withrelation to the dial-plate 215 by the weight of contents placed in thehopper, (See Figs. 10 and 12.)

A bearing-bracket 21 extends from the a l i member 181. and has rearing222 thereon, in which a shaft 2 is journaled. This shaft has a pinion22-1 lixed thereon which meshes with a rack 225 on the bar 200. Thebearing extends through the dial-plate 215.

The shaft compris s .Tuarc part 228, over which a hub 229 received torturning therewith. A finger 2230 has a bearing); 2 31 about the hub. astrip 23:2 being riveted to the hub. The finger comprises a pointerwhich registers with a dial 236 on the dial plate 215 and a pointe whichregisters with a dial 238 on the maisplate 216. (See Figs. 10, 12 and13.)

A spacing block 241 is fixed to the shaft- 223, as by being threadedover the outer threaded end 212 of said shaft. and having connectionwith the linger and its strip by means of a screw 213.

The ting-er is, adjustable with relation to the dial to cause itspointer to register with zero on said dial, accomplished by providingthe ta1l 2 l 1 of said finger with an areuate slot 245, through whichthe screw 2 13 passes. (See Figs. 13 and 1st.) A washer 24. 6 isreceived between said tail and the flange 2&7 of the spacing block 2&1for clamping said flange, washer, tail of the inger and the stripthereunder securely together in adjusted positions. The finger isrotatable about the hub 229 sufficientlyfor such adjustment.

The spacing block is provided with a ournal 243 on which the dial-plate216 is arranged to rotate for adpisting the same with relation to thedial-plate 215. 7 It is held in adpiste-dpositions by means of a springswasher 24.9. a clamp-washer 256 and a screw 251 threaded into thespacing-block and clamping the dial-plate 216 between the washers and ashoulder on said'bloclr.

The normal position of the dial-plate 215, is registry of its Zero markwith the pointer Referring to Fig. 10, the, dial 236 is instanced asdivided into pounds, and the dial 233 is also instanced as divided intopounds, similarly to the dial 236. The dial plate'216 is provided with acontactpart1 255, shown as a pin, which is arranged to strike an arm256, for Causing discontinuance of the feed into the hopper in manner tobe presently described. v V

The dial-plate 216 is adjustably positioned with relation to thedial-plate 215 so [as to place the marking thereon representing thenrunber of pounds of weight desired to be.

placed into the hopper in registry with the pointer 237 thereon.

Referring to Fig. 10, the dial-plate 216 is set for a desired weight ofsixty pounds in- .he hopper. During the time that flouris sifted intothe hopper and t well as the dialplate 216 will moveclockwise asrepresented in Fig. 7, until the pointer 235 registers withth'e numeralon the dial-plate 215, at which moment the pin 7 255 will have engagedthe arm 256 suliiciently to cause cessation of feedingv movement offlour into the hopper.

The cessation of feeding movement into the hopper in the presentinstance caused by release of the clutch 131. This release of p theclutch is effected by the power of the no weight ofv flour in the hopperincreases, the finger as and stresses caused'by different weights de.sired in the receptacle.

In the mechanism exemplified, the shaft 71 has a tube 261 lined thereto.This tube has a cam 262 thereon, exemplified as a screw cam. The tuberotates in the direction of the arrowa in Fig. 21. A pin 263 is arrangedto be 7 retracted when feeding movement of the flour into the hopper isto take place, as exem plified in Fig.21, which retracted positioncorresponds to an engaged relation of the clutch 131. parts, feedingmovement of'the flour into the hopper takes place. When the desiredweight offlour has been fed into the hopper, the retracted position ofthe pin ceases, and an extended relation of the pin, shown in Fig. 22,takes place, in manner to be presently described. 7 p

As soon as said extended relation oft-he pin takes place, it engages thelow pointof the cam 262 at the end of the tube 261, and moves the pinlengthwise of the shaft into the position shown in Fig. 22, which occasicns a release of the clutch and a cessation of feeding of thefiourinto the hopper.

The pin 263 is in a bearing 266 in a frame 267 of a box 268, which islined to a rod 269 by a set-bolt 270, the rod being slidable endwise inbearings 271 in the end-plates on the elevator cas ng. An arm 273 isalso fixed .to'

said rod, as by a set-bolt 274;, and has a fork 275 thereon, which isreceived in an annular groove 276 in the movable member of the clutch.The box 263 contains 'means for automatically releasing the pin, to bepresently described.

The engaged and'relcase relations of the clutch may also be controlledby an arm 278, having a handle 27 9 thereon, and having articulation 280with the rod 269. The arm passes through an eye 282 on a hanger 283depending-from the bracket 121. which eye serves as a pivot for saidarm, for shifting the rod 269 lengthwise and shifting the clutch intoengaged and into'disengaged relation. (See Figs' 1, 2 and 6.)

The means for automatically controlling the position of the pin isexemplified as an electric translating device, shown as an elec- Duringsuch relation of the.

tro-magnet 286. The electro-magnet is provided with an armature 287,hinged to the frame 288 of the electro-magnet by a pin 290, the armatureforming one of the arms of a horse-shoe magnet, which also comprises acoil 291, surrounding the core 292 of the magnet. (See Figs. 11, 23 andA link 295 connects the pin 263 with said armature, being receivedloosely through a slot 296 in an insulating bar 297 connected to horns298 of said armature by screws 299, and suspended therefrom by thehead300 of said 'link and a washer 301 thereunder.

The armature further comprises horns 305 to which a strip 306 is fixed,but insulated there'tron'i. A switch-arm 367 is provided with acontact-head 308 and has a pivotlug 309 received in a pivot-slot 310 ofsaid strip. (See Fig. 11.) A rod 311 has a head 312 received in a socket313 of said strip. Said rod passes through aoertures in said strip andin said arm, and has a spring 314 thereabout, held thereon by a washer31.5 and a pin 317, tor normally urging the switclnarm toward the strip306, which latter is provided with a lug 318 for limiting movement ofthe switch-arm toward said strip, and maintaining the pivot-lug in itspivotslot.

The head on the switch-arm is arranged to make contact with a contact319 fixed to a stem 320 in an insulating block 321, fixed to the frameof the automatic switch-box. A switch 322 is thereby formed, which isarranged to be automatically opened. (See Figs. 11, 23 and 24.)

lVhen this switch is automatically opened, the armature is released, andthe pin 263 drops into range with the cam 262 on the tube 261, fordiscontinuing the feed of flour into the hopper.

A switch-box 327 is fixed to the bracket 186. (See Figs. 2, 3, 10 and12.) It contains a normally open switch 328, comprising the contacts 329and 330, having a gap therebetween and arranged to be contacted by acontact 331, shown as a washer t electroeconductive material, at theinner end of the stem 332 of a push-button operating in a bearing 334 ofan insulating block being normally retracted by a spring 336 surroundingsaid stem, the spring being located between said button and saidbearing.

The contact 329 is one. bracket 339 fixed to said insulating block, andhas an electric conductor 340 from a suitable source of electric energy,as a public service station, connected therewith. shown in the form of awire received about a screw 341 in a fork 342 termed on said bracket.(See Figs. 12 and The screw is arranged to clamp said wire in said fork,and also serves as an adjustable contact of an automatic switch in saidswitch-box. The other contact of said switch is an arm 344 pivoted on abushing 345, (see Fig. 16), through which a screw 346 passes into saidinsulating block, an electric wire 347 being clamped between the head ofsaid screw and the outer end of said bushing for conducting electricitythrough said bushing and said arm. The i nsulated arm 256 is fixed tosaid arm 344, and extends through a slot 348 in said switchbox, into therange of the pin 255. (See Figs. and 12.) A steadying spring 349 islocated between the switch-bo2z and said arm for steadying said arm andpreventing unnecessary vibration thereot, it being understood that themovement of said arm is very delicate.

The contact-screw 341 may be adjusted by a screwdriver passing through ahole 350 in said switch-box, so as to locate the insulated arm in properposition with relation to the pin, so that, when the numeral on thedial-plate 216, corresponding to the desired weight of flour in thehopper and the pointer registers wit-h the similar numeral on thedial-plate 215, the contact between the arm 344 and said contact-screwis released, to interrupt the current through the magnet 286, wherebythe armature of said magnet drops for placing the pin 263 into rangewith the cam I have in Fig. 24 illustrated a desirable wiring diagram ofthe circuits 01' said magnet. Thus 354 represents a battery or othersuitable source of electric energy.

A wire 355 connects with one of the te r minals ot the battery and withthe wire 340, which connects with the automatic switch 343, from whichthe wire 347 extends, forming a partial circuit. The wire 355 connectswith an electric conductor 356, which connects with the manual switch328, with which a wire 357 is connected, forming a partial circuit. Thewire 357 is continued and connects with one of the terminals of the coilof the electro-magnet. The wire 347 is continued and-has connection withthe wire 357, and has in it the automatic switch 322 controlled by thearmature of the electro-magnet. A wire 358 connects the other terminalof the coil of the electro-magnet with the other terminal of thebattery.

I have in Fig. 11 shown the wire 357 secured to a binding post 359 inthe insulating block 321. The wire 347 has the automatic switch 322included therein and has electric connections with the binding posts 320and 359 respectively. The wire 358 is shown connected to a binding post360 in said insulating block.

The control means for controlling the interruption in -teeding movementof the material is exemplified as comprising a substant ally freelymoving member. instanced as the pin 263, which is normally held inuninterrupting position by the electric translating device 286 in anormally closed electric circuit.

As soon as the desired weight of material has been received in thereceptacle, the pin 255 makes contact with the arm 256 for moving thearm 344 away from the contact 341, whereby the closed circuit whichmaintains the interrupting member 263 in noninterrupting position,relieves the sustaining power on this member, which thereby, in thepresent instance, drops by gravity into interrupting position, forcausing opening of the clutch 131, the opening of the clutch being,however, effected by the power mecharsm, by coaction of the driven cam262 with said dropped pin 263.

1 It will therefore be noted, that the control means controls theposition of a substantiallyfreely moving member, so that itsactuationmay be most delicately controlled by the exact weightin thereceptacle for which the mechanism has been set, and that the actualcessation of the feeding of the material is caused by the powermechanism, which has abundant power to definitely and instantly causecessation of feeding of material, so that the amount of materialdelivered to the receptacle is always definite and exact.

In the present instance the controlled member is the pin 263, whichdrops by gravity immediately upon interruption of the electric circuitin the electric translating device 286, which motion is'substantiallyinstantaneous and occurs upon practically the instant of opening theswitch 34:3;

It is of course obvious that changes in construction and arrangements ofparts may be made from the exemplification of means herein shown anddescribed, without departing from the spirit of my invention asdisclosed in the appended claims.
